Asian Carp: The Invaders

In 1831, Asian squid was brought in as gourmet. Asian squid originally came from Asia (Barbara A. Somervill 13). They were imported by Koi farmers for federal research on the management of aquatic vegetation in 1963. In 1966, the first Asian squid escaped to the sea area of ​​Arkansas. By 1970, we kept carp in the waters of Arkansas to help excessive vegetation. In 1972 Arkansas state fish farmers brought big toads to America to improve his water quality and fish production.

In Canada, regardless of whether it was introduced from the Mississippi River or introduced through a salmon market, the Federal Fisheries and Ocean Ministry assessed the risk of Asian catfish penetrating Canada's waters, especially the Great Lakes. Large fish and carp were captured in part of the Great Lakes in Canada, but now Canada has no Asian squid (except for the original Eurasian squid). There is also concern that squid may spread through Battle Creek, French River, and other rivers flowing from the mountain to the Milk River to the Cypress Mountains in Alberta and Saskatchewan. The Milk River is a tributary of the Missouri River, and the population of Asian salmon is very mature.

The four Asian carp, big fish, squid, black bora, and glass coy are a threat to the Great Lakes fishing industry. Risk assessment of recently identified large fish, salmon and glass carps suggests that the Great Lakes are at great risk from these three species. The main threat to Asian catfish is the competition of food resources with other fish and the ability of these intruders to outweigh the local fish. The risk of black cockroaches is not evaluated. Like other intruders, the Great Lakes Fisheries Commission thinks that preventing the introduction and establishment of Asian catfish is the only effective way to maintain valuable Great Lakes fisheries.

It may still have catastrophic effects. Please look at the Asian squid and head to the Great Lakes. Longhorn Beetle in Asia (the recent intruder) also has caused tremendous damage to the forest of the country. The emergence of gray grasshoppers in emerald recently brought all these signs in the northeastern to say to people not to move firewood to avoid moving these invaders. There are zebra mule shells recently moved to Massachusetts, they take over the lake there, they are not there. This disease kills bats in the northeast and DC areas, which are invasive pathogens that are fungus. You can tell a name one by one. And if you do this story a year later, you will find a new conversation.
